ELECTRIC "AUTOOONDENSATION PAD. l

Application filed December 24, 1925. Serial No. 77,426.

This invention relates to an electric autocondensation pad for use of physicians 1n administering electro-therapeutic treatments, and has for its object to provide a pa-dfor this purpose which will consist of few and simple parts so that it may be manufactured conveniently and at a limited expense, will be eective in operation and will be convenient in use. One'of the specific objects in view is to provide a pad of this class which may be'rolled or folded to' form a compact package, vthis being a feature relating .to portability and convenience in use` The inH vention includes a' single, attenuated, metallic sheet disposed Within and maintained in separated relation from its flexible container or jacket.

VVit-h theforegoing objects in view and others to be mentioned hereinafter the invention presents a novel and useful construction, combination and arrangement of parts as described herein and claimed,and as illustrated in the accompanying drawing, Wherein,

Fig. l is a vieW of the pad in side elevation. Fig. 2 is a plan view, "the upper part of the pad being removed to shovv the single metallic sheet or electrode maintained invvardly of and adjacent to the side and end vvalls of the container or jacket. Figs. 3 and 4 show end views of the pad when rolled or folded to form a portable package. Fig. 5 is a view in longitudinal section showing a part of the pad. Fig. 6 is a view similar to tha't shown in Fig. 5, the scale being enlarged.

It is understood, of course, that electric pads have heretofore been used upon which patients might recline for treatments, these pads being provided with a plurality of metallic plates or electrodes electrically charged, said pads generally consisting of hingeably connected sections and each-section being provided with a rigid frame for containing an electrically charged metallic plate or electrode, but I am not aware that a single, flexible, elastic sheet has heretofore been used having such a degree of tenuity that the pad, together with said metallic sheet, may be rolled or yfolded to occupy a limited space, and which, on account of the resiliency of the electrode or sheet vvill normally assume a rectilinear shape, Whenvunrolled or unfolded.

In order that the objects first mentioned may be attained I provide la flexible container or jacket preferably of rectangular form in plan and elevation and constructed of leather, leatherette or similar material. Numeral 8 indicates a flexible, spacing-member or buffer conforming tothe area in plan of and disposed in the containeror jacket, preferably on the bottom thereof. Numeral 9 indicates a flexible, attenuated, elastic,

metallic sheet disposed on the buffer or spacing-member and secured in stationary relation therevvith by means of a pair of keepersor rivets 10.

The buffer or spacing-member preferably consists of a plurality of paper sheets conforming in size to the area of the jacket and of suchk consistency that theyvvill resist buckling from effects of end thrusts, but Will permit bending, and since the ends an'dside edges engage the respective ends andsides of the container or jacket there will be no sliding movement of the spacing member therein. f f

The ends and side edges of the electrode or sheet 9 are indicated respectivelyat L and and this electrode has such proportions that its ends and side edges terminate in- Wardly of the respective ends and side edges of the spacing-member or buffer; and on ac count of the keepers or rivets l0 the electrode Will have no swinging or sliding movementsrelative to said member 9, and there- `fore the sheet '9 will be prevented from incising or injuring the container of acket, it being understood that the degree of attenuation of the sheet 9 is very great and would readily cause incisions in the iexible jacket if not maintained inwardly of the ends and side edges of said member 8, and in spaced relation with reference to the jacket. n

Numeral 11 indicates a plurality of fiexible layers preferably consisting of paper sheets which are disposed above the electrode to operate as a stiffener for reinforcing the spacing-member 10, and any soft filler 12, preferably consisting of felt or cotton is disposed between the top of the pad and the paper sheets 11. At c is indica-ted a socket for a mounting of the electrical conductor d for electrically charging the elecor sheet .9 shall be Acompletely covered and housed zand prevented from oittting through the jacket.

Among some of the advantages to be derived yby use of the invention is vthe simple construction mentioned, the use of a llexible bul'er or spacing-plate, the simple andiprae tical means for maintaining the electrode inwardly of all of the edges `of the `spacingmember, and the use of a single attenuated elastic electrode whereby the ,pad may be Yrolled or iolded es shown 'in Figs. A8 'and l ot the drawing, ia-nd 'on yaccount fof 'the tenuity'and elestieityiof the `inetallie sheet and use of a 'flexible vspeGing-member lor butl'er, the Ypad will normellyfassume'a nee- `tilinear form las v4shonnin :11 lo'titheidiraw ing, when ,unli'olled or `sunlolded.
